摘要
文章介绍一种快捷方便的光伏电池故障检测及定位方法,适用于光伏智能控制器。利用Atmega16单片机芯片测量并记录正常工作状态下,光伏电池方阵系统的电压、电流值随光强改变时的变化情况,再将工作时系统的电压、电流参数与正常状态进行比较,如参数异常则可通过数据分析确定故障类型。Atmega16芯片控制光伏电池方阵中光伏组件个体间的电子开关,使光伏组件逐个脱离和接入电池方阵,在此过程中对光伏电池方阵进行电压、电流监测,通过数据分析定位故障位置,并将故障电池进行暂时隔离处理,确保光伏发电系统安全稳定运行。
This paper introduces a kind of quick and convenient method of fault detection and location for photovoltaic battery.This method is suitable for photovoltaic intelligent controller.Under normal working condition,using Atmega16 chip to measure and record the voltage,current of the PV array varying with the change of light intensity.Compared with the normal state,fault types can be determined through data analysis if the parameters of voltage and current are abnormal.Atmega16 chip controls the electronic switch between the individual PV in the PV array to disconnect and connect the PV to the PV array.During this process,Voltage,current of the PV array are monitored.Locate the fault position through the data analysis,and isolate the faulty PV temporarily to ensure the safe and stable operation of photovoltaic power generation system.
